Restore Full Electrical Function to Your GM Truck
Are you chasing down frustrating electrical gremlins in your truck? A faulty Body Control Module (BCM) is often the culprit behind a host of baffling issues, from a dead climate control panel to power windows that have a mind of their own. This OEM-quality replacement, part number 15284816, is the definitive solution for your 2011 Sierra 3500 Body Control Module needs. It arrives expertly pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a seamless, plug-and-play installation right out of the box.
Is Your Sierra Plagued by These Electrical Gremlins?
- ✔ Your HVAC controls are unresponsive, or the blower motor works intermittently.
- ✔ The airbag warning light is illuminated on the dash, often with a DTC like B1001 stored.
- ✔ Power door locks, windows, or interior/exterior lights are failing or acting erratically.
- ✔ The security system malfunctions, causing no-start conditions, stalling, or misfires.
- ✔ Your scan tool shows a variety of communication or body-related diagnostic trouble codes.
A Technician’s Notebook: The Intermittent Fault Fiasco
I had a 2011 Sierra 2500 in the bay last month that was driving its owner crazy. The radio would randomly shut off, the dome light would flicker, and occasionally the truck wouldn’t start. The battery and alternator checked out perfectly. After chasing wires and checking grounds (always the first step!), I hooked up my professional scanner and saw multiple communication loss codes with the BCM. These modules can fail internally in ways that don’t always throw a hard code, causing these ‘ghost’ problems. Swapping in a VIN-programmed BCM like this one solved every single issue in under 10 minutes. It’s the most common failure point for these symptoms.
A 5-Minute Fix: Your BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your truck’s battery before working on any electrical components.
- ✔ Locate the Module: The BCM is typically found under the driver’s side dashboard, to the left of the steering column. You may need to remove a lower dash panel for access.
- ✔ Swap the Connectors: The module has several large multi-pin connectors. Carefully depress the locking tabs and unplug them from the old BCM. Plug them securely into your new, pre-programmed module. They are color-coded and keyed to only fit one way.
- ✔ Secure and Reassemble: Mount the new BCM back into its bracket and reinstall any panels you removed.
- ✔ Power Up and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions: lights, locks, windows, wipers, and HVAC to confirm the repair. Note: If the airbag light remains on, a special procedure may be needed (see FAQs).

Frequently Asked Questions
What does ‘VIN Programmed’ mean for my 2011 Sierra 3500 Body Control Module?
It means we load your truck’s unique Vehicle Identification Number (VIN) and all related factory settings onto the module before shipping. This makes it a true plug-and-play part, with no need for a trip to the dealer for expensive programming.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module without any extra fees or hassle.
Why is my airbag light still on after installation?
If the airbag light is on, it means the new BCM needs to be synchronized with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. It’s a quick electronic handshake that secures the airbag system.
Are any special tools required for this job?
Typically, no. Basic hand tools like a socket set or a screwdriver to remove the lower dash panel are usually all that’s needed. The electrical connectors unplug by hand.
Will this fix my intermittent stalling or no-start issue?
In many cases, yes. The BCM plays a key role in the vehicle’s anti-theft and security system. When it fails, it can incorrectly immobilize the engine, leading to stalling or a no-start condition. Replacing a faulty BCM is a common fix for these symptoms.
